project process now is to a new level

before we got a final display board from Unitec, we determined to buy a one by ourselves first in order to get better design. After project calss, we again together went to Tony's workshop. Tiitii's task was to put all the EFI components nicely and logically on the board which we just bought from Bunnies warehouse. then make all the measurements we need for our final board.

this is the picture we took after Tiitii finished the drawing, we will basically design our project on this blueprint.
all i have to do was to solder the speed motor control unit which i have nerver done that before. the lucky thing is that Tony knows it and i asked him some technical questions then got started. it was fun at the beginning, however it really piss you off after a few try. it took me five hours to finally get it done. but i don't know if it will work, but we will know once we use it.

                                       after i finised the soldering, ugly is not it?


about Tiitii's board design, we have to discuss all the time to decide which way to put the components is the best. after we came to a final decision, we took some pictures as a part of our project. next week is the time to sign the contract with our supervise. once we get his satisfaction, we can really start to do our project. our project.
 
                                      
we used one of the sides of the board to arrange the components so we can decide the best way to put them.

meeting with our supervisor

to build the speaker motor control unit, i went to jaycar. so lucky that they have the unit in a kit. all i have to do is carefully to read the instruciotn then build the unit step by step. not very hard, but do take me a while to understand how it works. the only thing left out is that i have to solder them together. that will be done in Tony's workshop.
time goes by fast, the second class on TP came up. when every group is talking to the supervisor about their ideas, we actually have started to build our project. after class we had a meeting with Prahbat. he wants us to finish this project very professionally. that will be really a challenge to us all. and in the following week we have to show him our process on:
1: the project layout plan
2: wiring diagram
3:lists of parts
4: size of the board
we went to Tony's workshop again to put all exsiting components in a logical way and decided to buy a board first then try to make it work

very exciting

i have heard of that technology project will be a hard ass. luckly enough, on the very first class on TP, Tony came up with a brilliant project and offers Tiitii and me to be partners of his. what a honor. that would really save us a lot of time and we can start the project right away. with Tony's knowledge, i believe that we can push our project to a very high level.
after class, we had a meeting among three of us. the project that Tony has is to build a EFI system. we have to clearly demonstrate the fuel formation and spark. without working with the eninge, how to simulate vacuum would be a real challenge to us. i  did some research on how to build our own vacuum pump and came up with two ideas:
1; use a  fridge compressor unit and other componets to build one
2: buy a  electric vacuum pump used on Ford diesel engine
the first one is obvious a little bit complex and hard to control
the last one we can simply control it by using a potentiometer to work with
but how it goes, will depend on the process we are making on the project
to further throughly understand the project, Tiitii and i went to Tony's work shop. he has disassembled a whole EFI system from a old TOYOTA COROLLA. we will put these components onto a white board to make them work. a speaker control motor would be used to play the part of  the engine.
to share the job, Tiitii will make a drawing for the board
and my job is to build a control unit to control the motor speed
